[Why] At the end of the Western Han, consort kin held power, the bureaucracy was corrupt, and land annexation reached the limit of popular endurance. Society broadly yearned for a Confucian-orthodox sage to cleanse the long-standing illnesses of the court. [What] Wang Mang built moral reputation through cultivated virtue and finally deposed the boy emperor, founding the Xin dynasty. Invoking antiquity, he imposed radical reforms including the Wang Tian land system and repeated currency overhauls. [Who] Wang Mang typified the consort-kin reformer steeped in Confucian classical idealism but devoid of administrative common sense. The vast peasantry crushed by his chaotic currency policies were the innocent victims of his reforms. [How] The failure of the reforms ignited the nationwide Lulin and Chimei uprisings, collapsing the Xin in an instant. It became the most painful Chinese case of Confucian utopian idealism shattering against political reality.
